the corona virus (SARS-CoV-2) will have an indefinite impact on global society and thus on all of us. Today we would like to inform you personally about how ASCO CARBON DIOXIDE is dealing with the current situation. We assure you that we are doing everything to ensure the continuity of our services & products for all our customers around the world.

For ASCO CARBON DIOXIDE, the health and safety of our employees and business partners are decisive elements of our corporate culture. Not least for this reason, we follow the recommendations of the World Health Organization as well as national regulations to slow down the spread of the virus as much as possible. As a result, we have asked some of our employees to work from home as a precaution. Be assured that we are still available for you and your concerns through modern communication possibilities.

Nevertheless we would like to inform you that due to the extraordinary situation ASCO has limited all business trips (including service interventions) to the absolutely necessary minimum. For current and future projects, unforeseen delays may unfortunately occur, as we are also dependent on our suppliers and cooperation partners. The communicated delivery times of your orders and inquiries are currently still feasible. We will inform you individually, should this no longer be guaranteed.

We thank you for your understanding and are available at info@ascoco2.com or +41 71 466 80 80.

General Information about Dry Ice

Dry ice is the name for solid CO2. At atmospheric pressure it has a temperature of approx. -79° C (-110,2 °F). The evaporisation is residue free. Dry ice is non toxic, non flammable, inert, tasteless and odourless. It is white and has a density of approx. 1'500 kg/m3 (93,64 lb/ft3)in its compact form.

Applications of dry ice

Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.

ASCO Dry Ice Blasting is a powerful, gentle, dry and ecologically friendly cleaning method causing no secondary waste. It is applied in many industries. For the cleaning of surfaces with our ASCO dry ice blasting technology dry ice pellets with the diameter of 3 mm (0,12 in) are standardly used. Dry ice pellets with a diameter of 1.7 mm (0,06 in) can also be used for the cleaning of delicate surfaces. For cooling purposes dry ice blocks and pellets with a bigger diameter are used.

How dry ice is produced

Dry ice is produced from liquid carbon dioxide (CO2). Inside a dry ice pelletizer, the liquid carbon dioxide is expanded under controlled conditions to form dry ice snow. This snow is then pressed through an extruder plate into round, hard pellets (elongated grains with a diameter of 3 mm or 1.7 mm according to the used extruder plate) for dry ice blasting purposes or into larger pellets/dry ice slices/blocks for cooling purposes.

Dry ice for cooling purposes

Dry ice is an ideal cooling media which can be used for many applications. It has a high cooling capacity. Dry ice blocks/slices or dry ice pellets are used for cooling purposes.

In-house dry ice production

In-house dry ice production starts paying at a need of several hundred kilograms dry ice per week. ASCO is in a position of providing interesting all-in-all CO2 concepts, these can be realised without making any major investments.

Advantages of an in-house dry ice production:

Less dry ice loss due to sublimation

More flexibility as you always have freshly produced dry ice at your disposal

Better and faster cleaning results because the fresher the dry ice, the more effective the cleaning
